A CHEMICAL COATING FOR BALLAST TANKS

After describing the characteristics of his firm's Magnakote, a sulphonate product introduced some time ago for the protection of ballast tanks against corrosion the Author (of Magnus Maritec International Inc.) describes a solvent-based new product, having the same corrosion inhibitor but using a resinous compound instead of tung oil as the carrier, which his firm has developed. This new ballast-tank coating, Magnaflex, is designed especially for new construction. The resin compound enables it to be applied at a much greater thickness than Magnakote, and it gives a harder (but not brittle) coating which has a longer life; application by airless spray is essential. For long life, the preparation for application in ballast tanks and similar spaces should be at least to Sal standard; any coating thickness can be built up, and a dry film thickness of 100 microns can be obtained without run-off problems. Magnaflex can also be applied to such parts as deck pipelines and winches. The coating, which depends on polar attraction and chemical reaction, is not a paint and will not adhere to a painted surface; it can be removed with any solvent-type degreaser.
